If you inject the oil too close to the exhaust outlet it will simply blow the unvaporized oil out the muffler. You actually want to inject the oil in a place where it will pool in the muffler and boil away.
i hate to contradict a LHS owner, God only knows how much great information they give out but...........i inject my smoke oil directly into the muffler where the engine exhaust port enters the muffler and it defiantly doesn't puddle up anywhere in the muffler yet it does a fair job of smoking IMO.

EDIT: my best guess would be your dead sticking is caused by the puddle of smoke oil you have in the muffler
